Some of the ABS data are currently not monitored with an alarm
handler and need to be monitored by using a check list.
Important ABS data are displayed on the target web page as a one
minute summary page:
http://blast.lns.mit.edu/targets/abs_web/documents/ABSinfo.html
and as a 24h graphical overview with updates every 5 minutes:
http://blast.lns.mit.edu/targets/abs_web/index.php?name=ops_ABS_online
Use shift-reload update the pages.
I have attached a file that shows current data of the ABS in
stable running conditions with flipping activated. Values that
should not depart significantly from the values on the sample
page are marked with a '*'. Significant means by a factor of
two or more. The 24h overview usually shows very stable
operation. Please go over the list and check the data on a
regular basis a couple of times per shift.
Every 5 minutes the target flip will cause a sudden increase
in the target pressure and the pressures in the compression tubes
BRP-Up and BRP-Down. There is no need to be alarmed about this.
